Some special high-performance tires have unidirectional treads: their tread pattern is designed to work better in one direction
than in the other. The sidewall marking of a unidirectional tire will have an arrow showing the correct rotation direction. If your
bike has unidirectional tires, be sure that they are mounted to rotate in the correct direction.
2. tire valves
The tire valve allows air to enter the tire’s inner tube under pressure, but doesn’t let it back out unless you want it to. There are
primarily two kinds of bicycle tube valves: The Schraeder Valve and the Presta Valve. The bicycle pump you use must have the
fitting appropriate to the valve stems on your bicycle. All eZip and iZip bicycles use Schraeder valves
The Schraeder is like the valve on a car tire. To inflate a Schraeder valve tube, remove the valve cap and push the air hose or
pump fitting onto the end of the valve stem. To let air out of a Schraeder valve, depress the pin in the end of the valve stem with
the end of a key or other appropriate object.
The Presta valve has a narrower diameter and is only found on bicycle tires. To inflate a Presta valve tube using a Presta
headed bicycle pump, remove the valve cap; unscrew (counterclockwise) the valve stem lock nut; and push down on the valve
stem to free it up. Then push the pump head on to the valve head, and inflate. To inflate a Presta valve with a gas station air
hose, you’ll need a Presta adapter (available at your bike shop) which screws on to the valve stem once you’ve freed up the
valve. The adapter fits the end of the air hose fitting. Close the valve after inflation. To let air out of a Presta valve, open up the
valve stem lock nut and depress the valve stem.
Bicycle suspension
Some bicycles come equipped with suspension systems which are designed to smooth out some of the shocks encountered
while riding. There are many different types of suspension systems — too many to deal with individually in this manual. If your
bicycle has a suspension system of any kind, consult a qualified specialist to provide you with the appropriate adjustment and
maintenance instructions.
WaRninG: Failure to maintain, check and properly adjust the suspension system may result in suspension malfunction,
which may cause you to lose control and fall.
caution: Changing suspension adjustment can change the handling and braking characteristics of your bicycle. Never
change suspension adjustment unless you are thoroughly familiar with the suspension system manufacturer’s instructions
and recommendations, and always check for changes in the handling and braking characteristics of the bicycle after a
suspension adjustment by taking a careful test ride in a hazard-free area.
